So found my sheet with measurements from center of trunnion to center of roller
SBC 1.420
BBC1.650
BBF 1.590
SBF Windsor 1.508
HS Pontiac 1.508
HS Race Body Pontiac 1.535
I sure thought I remembered the Crower SBF was shorter than the Pontiac I will have to dig out the 1.6 and the 1.33 break in rocker and measure again. But as you can see a BBC is 0.142 longer if you are not using the 0.090 offset trunnion. Does not make sense it could fit unless a really short pushrod. My 0.090 BBC take a 8.950 pushrod vs a 9.150 for the HS Pontiacs.
